Filed: 1997-02-12
Abstract: PROBLEM TO BE SOLVED: To perform a display of multigradation independently of time control by freely changing brightness of an organic EL element in controlling a current supply circuit by a current changing means. SOLUTION: At the time of making the organic EL element 11 emit light, a data signal DATA1 outputted from a latch circuit becomes a light emission signal to be inputted to a bias changing part 230 connected to an anode side terminal Po1. On the other hand, gradation signals D11-D1k are inputted to a switching element group 232, and a bias to be set by a bias changing part 230 is decided in accordance with these gradation signals D11-D1k. Consequently, a transistor 231 is worked under the decided bias, and finally, a current depending upon the gradation signals D11-D1k flows into the organic EL element 11, and hence light is emitted by the organic KL element 11 at a degree of brightness. This brightness is decided by the gradation signals D11-D1k, and the organic EL element 11 is made to emit light by multigradation without controlling a light emitting time.

Title: Ultrasonic wave generating body
Inventor: KARAKI KOICHI
IPC: H04R17/00
Filed: 1992-02-14
Abstract: PURPOSE:To obtain an ultrasonic wave generating body with which high transmissivity can be obtained by providing a reflection preventing film made of C60, C70, or a mixture of C60 and C70 on the ultrasonic wave radiating surface of the body. CONSTITUTION:An antireflection film 3 made of C60 (or C70) is formed on the curved ultrasonic wave radiating surface of an acoustic lens main body 1. The C60 and C70 which are substances having low-densities and low-acoustic velocities have extremely low densities due to their molecular structures (soccer ball structures) and the structures formed when their molecules construct crystal structures as solids and their acoustic impedances become about 4X10<5>g/cm<2>.S. Therefore, when such an antireflection film 3 is provided on the ultrasonic wave radiating surface, the characteristic, especially, transmissivity of the acoustic lens can be remarkably improved and, for example, the transmissivity at the boundary between liquid helium and sapphire becomes about 18%. Thus the transmissivity of this acoustic lens can be improved as compared with the conventional acoustic lens.
